The i-StARS starter-alternator combines the functions of two normally distinct devices: the starter, which starts the engine, and the alternator, which produces the electricity the car needs. The combination of these two functions in the same product ensures the stop-start functionality and also provides a light hybrid solution, called micro-hybrid.
The i-StARS starter-alternator is a non-invasive solution in terms of engine architecture. It replaces a conventional alternator and the fact that the power and control electronics are integrated at the rear of the device make it easier to install in the engine compartment. The i-StARS starter-alternator is compatible with both manual and automatic transmissions.
In alternator mode, the unit’s power electronics improve its output. In starter mode, the device provides a silent, vibration-free, instantaneous engine start (400 milliseconds), thanks to a permanent link to the crankshaft through the belt drive.
The i-StARS starter-alternator adapts to all stop-start situations. It stops the vehicle engine when the speed drops to below 8 km/h for automatic transmissions and 20 km/h for manual transmissions, when decelerating.
